Challenge 4: Water Cycle, Weather, and Climate

What is the effect of temperature on the evaporation of water?

• The lower the temperature the higher the evaporation rate.

• The higher the temperature the higher the evaporation rate.

• The higher the temperature the lower the evaporation rate.

• There is no relationship between temperature and evaporation rate.

The atmospheric pressure plays an important role in the water cycle. Which of the following best describes the outcome as a result of an increase in atmospheric pressure?

• The precipitation decreases.

• The rate of evaporation increases.

• The condensation rate decreases.

• The evaporation rate decreases.

Bernie put some ice in a cup and poured some cold tea over the ice. He set the filled cup on the kitchen table. In a few minutes he noticed that there were drops of water all over the outside of the cup. Where did the drops of water most likely come from?

• They evaporated out of the air above the cold liquid.

• They condensed out of the air surrounding the cold cup.

• They dripped off the ice cubes as he put them into the cup.

• They came off his hands after holding the melting ice cubes.

If Walter puts a bucket of water out in the Sun on a hot, windy day, what will happen to the water level in the bucket?

• The water level will go down as the water evaporates from the bucket.

• The water level will rise as water condensates from the air above the bucket.

• The water level will stay the same since the water is protected from the wind.

• The water level will only go down if the wind makes water splash out of the bucket.

Which answer best explains why clouds usually form high in the sky?

• It is cold enough there for the water vapor to begin condensing.

• It is warm enough there for evaporated water to expand into clouds.

• It is dry enough there for precipitation to form from condensed water vapor.

• It is windy enough there for water droplets to get pushed together into clouds.

Padma took a bottle of water with her when she went to play soccer. She wanted to make sure none of it evaporated from the bottle while she was playing. What should she do to keep the water from evaporating?

• Screw the top on loosely and set it in the Sun.

• Put the top on tightly and leave it in the shade.

• Leave the top off the bottle and set it in the Sun.

• Screw the top on loosely and keep it in the shade.

As weather gets colder, the air pressure goes up. Why does this happen?

• As the temperature drops, the air takes up more space and presses down harder on the ground.

• Colder weather makes the air denser, and increased weight of the air means that there is more air pressure.

• Cold weather causes Earth to cool, and the heat that leaves Earth pushes against the air and increases pressure.

• When the weather is colder, the clouds weigh more as ice begins to form. The heavier clouds increase the air pressure.

If you examine a piece of hail, it might have visible layers like an onion. Which answer best explains why this is true?

• As hail falls, it picks up layers of dust and dirt from the air.

• Hail forms layers because it melts as it falls toward the Earth.

• Air pressure increases while the hail falls and it causes ice layers to form.

• Hail builds up ice layers as it travels through updrafts in a storm before it falls.

Constance wondered what caused the wind to blow and how reliable wind energy is in providing electricity to the factories and schools in the area. Which is the best explanation about the cause of moving wind?

• Currents from outer space cause the turbines to move.

• Uneven heating of the Earth results in a pressure gradient force.

• The revolution of the Earth around the Sun causes wind currents.

• Wind is fueled by wind turbines that receive electricity from power lines.
